More Information
Summary:The invention relates to a preparation method for fructooligosaccharid, specifically of hydrolyzing American artichoke to prepare fructooligosaccharid by means of column ion-exchange treatment, including: 1) preparing the American artichoke liquid; 2) treating the prepared extract with calcium hydroxide, airing the CO2 gas, precipitation centrifugal filtering to get transparent American artichoke liquid; 3) treating the American artichoke extract with cation exchange resin controlling the velocity of flow at 800-1200cm3/h, discharge liquid pH value between 1.0-2.2; 4) dispositing the discharge liquid in room temperature for acidolysis 2-6 hours, passing through strong anion resin, concentrating the liquid, spray drying or drying in vacuum. The invention removes the impurity in the chicory by ion exchange resin, simultaneously reduces its pH value, controls the acid leaching time. Compared to the enzyme method, the present method can get a comparative product in purity, but a lower production cost. The method paves a foundation in the large-scaled for fructooligosaccharid with a simple craft, timesaving and powersaving.
